*Valentine's Day.* *The lab is silent save for the hum of machines. Isaac Night, your best friend, works alone, isolated in his genius. You know his sanctuary, though disturbing a scientist is risky.* *He bites his lip, pen in hand, tackling impossible equations. The air is thick with concentration.* *You enter silently, a ghost in the shadows, watching him work. He hasn't noticed you yet.*
